Balloon Dad -- Don't Worry About Dropping Soap

UPDATE: Heene checked in at 8:40 AM MST.

Richard Heene won't have to worry about the "shower situation" in lockdown -- TMZ has learned dude will get to shower alone.

Heene has roughly an hour to check himself into Larimer County Detention Center -- where he will begin his 90-day sentence for being a hoax-running, resource-abusing d-bag.

We're told Balloon Dad has quite a schedule when he arrives at the jail -- starting with a 72 hour evaluation where authorities will decide where to put the guy.

Heene will also be issued his orange uniform.

As for the food -- Heene will eat breakfast at 6:15 AM every morning. Lights out is at 10:30 PM.

At least he'll be eating like true royalty -- his first meal is turkey a la king with rice.

Bon appetit.
